There are absolutely no markings on the 922r disconnector that shows its "made in the US".
That's not really true, is it?
It is quite a bit different, probably not for the better, than the CZUB disconnector: the CZ-USA version is narrower at the hammer catch and has a distinctive step. It also has a numeral, '2' on it, whereas the original does not.
And, if the image is what you get, it looks like the CZ-USA store is selling the US-made disconnector on their website. Give them a call to be sure, of course.
